After living and training throughout the country, I am excited to be part of the Stanford team. As a result of both my personal experiences and training, I am passionate about ensuring that patients receive appropriate diagnostic testing and treatment options in order to improve people's quality of life. In collaboration with my amazing colleagues, I am confident in the high quality and easily accessible care we are able to provide to patients across northern California.
